Don’t know if that one is also mantained by you.

syntax error : ‘bad suffix on number’

As you can imagine it is quite annoying to go through all the vertices (that don’t have a decimal point) adding the decimal point so it compiles correctly.

Is it possible that you could fix your exporter so it writes the numbers correctly with their decimal point.

Eg.: write 10.0f instead of 10f.

Thanks

i had a model that was not triangulated. I imported the .obj in Blender and re-exported it to .obj with the “triangulate” option on. After that operation the model showed correctly but texture looked messed up. I tried to figure out what was happening looking at the script. I noticed that you flip the v coordinate when parsing the file. In my case that was a problem (don’t know why you were doing such a thing but i’m sure you have your reasons). I solved the issue by changing line 358:

$y = 1 – $tokens[2];

to

$y = $tokens[2];

Now everything renders correctly. Note that i had the same problem with your banana.h file (i used it “as-is” without importing/exporting with blender). I’m using these models with Qualcomm AR and the standard glDrawArrays call.

Anyway great tool and thanks for making it free!

Any help please…

Where does the header file go?

Would I have to use the NDK to include the header?

Thanks.

For ex: I want to get following texture object – c header file to mapping.

#import “OpenGLCommon.h”

#pragma mark Pineapple

static const TexturedVertexData3D PineappleVertexData[] = {
{/*v:*/{-0.077927, -0.104604, 49.076447}, /*n:*/{0.000000, 0.174718, 0.984588}, /*t:*/{0.056455, 0.679422}},
….
}

#define kPineappleNumberOfVertices 402
// Drawing Code:
// glEnableClientState(GL_VERTEX_ARRAY);
// glEnableClientState(GL_TEXTURE_COORD_ARRAY);
// glEnableClientState(GL_NORMAL_ARRAY);
// glVertexPointer(3, GL_FLOAT, sizeof(TexturedVertexData3D), &PineappleVertexData[0].vertex);
// glNormalPointer(GL_FLOAT, sizeof(TexturedVertexData3D), &PineappleVertexData[0].normal);
// glTexCoordPointer(2, GL_FLOAT, sizeof(TexturedVertexData3D), &PineappleVertexData[0].texCoord);
// glDrawArrays(GL_TRIANGLES, 0, kBanana1NumberOfVertices);
// glDisableClientState(GL_VERTEX_ARRAY);
// glDisableClientState(GL_TEXTURE_COORD_ARRAY);
// glDisableClientState(GL_NORMAL_ARRAY);

How to get this style header file. using what tool from where?
And is this possible to get in Autodesk 3Ds Max?

How to get .pvrtc file not pvr. I could PVRText Tool, TexturePack Tool, etcc. but this is not supported.

Thanks.

EveryOne!!!

I can’t seem to get QCAR sample working like you do. Would you be so kind to contact me through twitter and perhaps share you sample project with me?

Nothing gets drawn even when using glDrawArrays, do i need some changes elsewhere?

Thanks!

Last post of convertor had international problems with decimal point.

The app : http://www.freedrive.com/file/1580559

have updated application now create’s a delphi unit that will load object file with all texture’s.
the file has to be 3ds max triangle.

you will need

DglOpengl.pas : http://www.freedrive.com/file/1580561

Textures : http://www.freedrive.com/file/1580562

whttp://www.freedrive.com/file/1580096

also this is where i have posted script for delphi unit

http://www.freedrive.com/file/1580099

i could change polygon data on QCAR sample “ImageTargets” using “banana.h”(sample code : obj2opengl)

i must use glDrawArrays() instead of glDrawElements().that’s only.

——————–
File:ImageTargets.cpp
——————–
line:401-

glVertexAttribPointer(vertexHandle, 3, GL_FLOAT, GL_FALSE, 0, bananaVerts);
glVertexAttribPointer(normalHandle, 3, GL_FLOAT, GL_FALSE, 0, bananaNormals);
glVertexAttribPointer(textureCoordHandle, 2, GL_FLOAT, GL_FALSE, 0, bananaTexCoords);

and

line:417-

//use glDrawArrays() instead of “glDrawElements”
/*
glDrawElements(GL_TRIANGLES, NUM_TEAPOT_OBJECT_INDEX, GL_UNSIGNED_SHORT,
(const GLvoid*) &teapotIndices[0]);
*/
glDrawArrays(GL_TRIANGLES, 0, bananaNumVerts);

——————–
terminal:ndk-build -R
eclipse: build -> clean

thanks a lot.

Now,I’m trying to use it with QCAR(AR Utility on Android/iPhone) to change polygon data in Sample source,”Image Targets”.

sample code in QCAR “Teapot.h” have 4 variables
(teapotVertices/teapotTexCoords/teapotNormals/teapotIndices).
but,”obj2opengl” outputs only 3variables(bananaVerts/bananaTexCoords/bananaNormals).

how can i use obj2opengl for QCAR?
i’m not good with OpenGL,and i know it’s not obj2opengl’s problem..

from japan

it loads all the texture’s, I have got it to display the object and textures, but not any special stuff, Can you tell me where i Can get some good information on the obj file that a begginer can understand, I need to know what all the information is used for in Basic opengl.

Not sure if this will work for everyone but it worked for me. Good luck

Thanks for help.

I have the same error as the other two guys:
Here is how I created by Cube model:
Open 3DSM -> new cube.
Follow any tutorials to create texture.
Export as .obj

Where can I find more .obj models with a single texture image like the banana sample?

Thanks.

I am 3d modeler. and i wants to do some ar stuff for iphone.
for that i need to export my 3ds max model to opengl code
is it possible to export 3d model from 3ds max application
how can i export. can u plz advise me step by step

Please Reply

Raj

Any ideas?
